Lone Pine portrays an imaginary line situated in the Pacific North West between Spokane in Washington State and Klamath Falls in Oregon.

The layout supposes that, during the railway boom of the 1920s, the Great Northern Railway believed the existing route through the Cascade Mountains would not be able to handle the growth in freight and decided to build a parallel line through the mountains. However, due to the great depression of the late 1920s, the line became little more than a branch line.

The period is the late 1960s before the formation of the Burlington Northern and stock from the constituent companies, the Great Northern, Chicago, Burlington and Quincy and Northern Pacific can be seen alongside the occasional visitor from the Southern Pacific. Great Northern 'Big Blue Sky' livery is beginning to appear on the freight stock and the colours of the Union Pacific, Milwaukee Road and Rock Island Line can also be seen.
